TunnelCraft
by Palpex
With TunnelCraft installed, a server owner can share a Minecraft world without port forwarding, using a persistent address that players reach from an unmodified client.
What it does
The mod sends player traffic over a WebSocket relay built for this purpose, so a host can open a world or server without changing router settings or owning a public IP. The host installs the mod, starts it, and receives an address that stays the same across sessions and can be passed to friends. Joining players use an unmodified Minecraft client and install nothing. LAN worlds and dedicated servers are both supported.
Fabric API is required, and the mod is published for Fabric and NeoForge, with plugin builds for Bukkit, Paper, Purpur, Spigot and Folia on server platforms. Files cover 1.21 – 26.2 across 16 release versions. Exact compatibility depends on the release chosen, so the Versions tab should be checked before any file is taken. The environment is client and server, and the code is released under the Creative Commons Attribution Non Commercial 4.0 license, which is not open source.
Key features
Persistent server address
A connected server gets a TunnelCraft address that remains the same from one session to the next.
Relayed standard connections
Standard links pass the server's traffic through the relay, so no port setup is needed on the host's side.
Premium port forwarding
Premium users can forward additional TCP and UDP ports for mods, plugins and services, each on a separate connection.
Relay status monitoring
A public relay status page shows whether the relay network is operating.

How it compares
KmDDNS is server-side only and open source under the MIT License, for Fabric and NeoForge across 1.21.1 – 1.21.11, and uses a dynamic DNS approach instead of a relay. No More LAN is client and server, licensed under the MIT License but not open source, for Fabric on 1.21.11 – 26.1.1, and it targets LAN play. Port Bridge is server-side only and open source under the MIT License, for Forge and NeoForge across 1.21.1 – 1.21.11, and it forwards ports rather than relaying traffic.
